Hi folks:
I'm new to the group but wanted to take a minute and pick everyones
brain. :-)
I have a TS50 thats loosing power. The lower in freq you go, the worse
it gets. Just curious if you guys would have an idea of what I should
be looking for and what it might take to repair.
On 10 mtrs the rig has about 80 watts output. On 80 mtrs it has about
20 watts. this is tested into a good 50 ohm load so no mis-match to
consider.
Any ideas??

Thanks & 73: Jerry N0JRN

The first step is to check the current draw. If it goes up as the
power goes down then there is a problem in the LPF networks after the
final unit. Most likely a stuck relay.

If the current draw goes down as the power goes down then it's a lack
of drive and most likely in the BP filters in the RF unit.

Check those and get back and we can go from there.

Do you have a service manual? If not try and buy, borrow, or download
one from somewhere. It's almost necessary to find the various points
needed to troubleshoot a radio.
